Effects of salinity in seed germination of Trigonella foenum-graecum and Hordeum vulgare

Introduction

Effects of salinity in seed germination of Trigonella foenum-graecum and Hordeum vulgare Introduction Land and water are essential for agricultural production, when water supply is enough for the plants, then the quality of water, soil and environment is most important to the plants (Villagra and Cavagnaro 2005). For the purpose of this report, Salinity can be defined as the build-up of salts in the soil and water or other media, which also can affect plants germination and growth. Salt is effect to all living species, plants and animals are forced to suffer from caustic amounts of salt in the freshwater supplies. Salt significantly reduces some of salt sensitive plant growth, root and shoot growth are reduced and tip burn is increased. The reason of this is salts can produce decreased water uptake, instability in metabolism and nutrient ingestion (Villagra and Cavagnaro 2005). For example, strawberries, lettuce, and avocados are especially sensitive to salt content in their irrigation water (Branson and Gustafson 1971). Australian Bureau of Statistics (2003) ...read more.

Secondly, soak the seed by fully cover 50 seeds in 3 different concentration of solution for 24 hours in the dark respectivelly. Following, germination dishes were prepared by putting wet blotter paper and labeling for three containers. Then, 40 presoaked seeds from 3 treatment groups were added to the matched container and replaced lid. The seeds started to germinate after period of time, the record the number of seeds germinate in each container everyday. Results The number of seeds that germinated in different treatment group was all decreasing by the increasing salinity (Figures 1, 2 and 3). Moreover, the number of fenugreek seeds germination is more than number of barley seeds germination by different concentration, as 20 fenugreek seeds germinate at 600 millimolar NaCl solutions (Figure 2), but no barley seed germinate at 600 millimolar NaCl solutions (Figure 3). Also, all the most number of seeds germinated in the control solution which is 0 millimolar NaCl solutions(Figure 1, Figure 2 and Figure 3). A significant increase of germination frequencies in the presence of NaCl was observed in seeds from salt-treated plants, as compared to seeds from control, non-treated plants. ...read more.

Conclusion

It may be states that individual experiment was established in a correct way, and environment for the seeds was pretty average condition. Refer to graphs, germination of fenugreek seeds are much more than barley seeds between class data, likely, there are 20 seeds germinated in highest salt concentration treatment, but no barley seed germinated in this treatment. It can be concludes that these two plants have different levels of salt tolerance. Reference (Villagra, P.E. and Cavagnaro, J.B. 2005) Villagra, P.E. and Cavagnaro, J.B.

    Three species of dipterocarp seedling were selected for study. Hopea sangal, Dryobalanops lanceolata and Shorea macroptera were chosen because they co-exist in dipterocarp forest and have differing ecological characteristics (Ashton 1964). S.macroptera is a light hard-wood fast growing species and requires high light intensity to regenerate.
